  Sorry, but the ABP framework does not support it

  Thank you very much.

  However, it occurs in the future that we want to separate DB instances. As a use case, ・Enterprise companies ・When the number of companies reaches a certain number, we want to split the DB (e.g. 1 DB instance per year)

  ●Question If we customize ABP Commercial to achieve this, can we get consulting? Also, is the scope of influence of customization quite large?

  ●workaround Given the current constraints, I would take the following approach ・xxx-2023.portx.cloud → 2023 DB ・xxx-2024.portx.cloud → 2024 DB

  Hi,

  This sounds like a DBA thing.

  For the code side.

  you can dynamically replace the connect string.

  Server=localhost;Database=xxx-{year}.portx.cloud ;Trusted_Connection=TrueTrustServerCertificate=True

  [Dependency(ReplaceServices = true)]
  public class MyMultiTenantConnectionStringResolver: MultiTenantConnectionStringResolver
  {
      protected ICurrentTenant CurrentTenant { get; } 
      
      public MyMultiTenantConnectionStringResolver(IOptionsMonitor<AbpDbConnectionOptions> options, ICurrentTenant currentTenant, IServiceProvider serviceProvider) : base(options, currentTenant, serviceProvider)
      {
          CurrentTenant = currentTenant;
      }
  
      public async override Task<string> ResolveAsync(string connectionStringName = null)
      {
          var connectionString = await base.ResolveAsync(connectionStringName);
  
          if (CurrentTenant.IsAvailable)
          {
              connectionString = connectionString.Replace("{year}", DateTime.Now.Year.ToString());
          }
  
          return connectionString;
      }
  
      public override string Resolve(string connectionStringName = null)
      {
          var connectionString = base.Resolve(connectionStringName);
  
          if (CurrentTenant.IsAvailable)
          {
              connectionString = connectionString.Replace("{year}", DateTime.Now.Year.ToString());
          }
  
          return connectionString;
      }
  }

  thank you.

  Is it possible to write the DB endpoint in this URL? https://docs.abp.io/en/commercial/latest/modules/saas?&_ga=2.31513790.1017473141.1680852494-480170447.1680614778#connection-string

  For example, for a company tenant, I want the host to be a.rds.cloud.

  Server=a.rds.cloud;Database=a;Trusted_Connection=TrueTrustServerCertificate=True
